fisrt sorry for my bad english
I think both boards are pretty good but they are very different.
I think the flare 99(2007)feels like a freerider with a bit of a freestyle touch. It feels way shorter than it extually is and thanks to de heelchutters it cranks upwind I like that because you can do more moves. but it doesn't lie as loose on the water as I want it to (the ahd fs feeling is great if you know what I mean). It's a great board for people who want to do freestyle but also look for a confortable ride.
the freesex (2005) This is more a real freestyleboard but it doesn't cruise like the flare
I like the freesex better because I don't want to cruis a lot.
